Last week a farmer found human bones in the south Rockhampton rural area, which has now been quarantined.

Detective acting Superintendent Bruce McNab says he can't specify how long it will take to identify who the bones belong to.

The bones belong to a man.

He says detectives have medical records for Mr Martinez and Ms Barnett but there are several variables that have to be taken into account before a positive identification can be made.

An earlier report suggested the bones may have been female, however, they are male. The Bulletin apologises for any inconvenience this may have caused.
